The surface circulation of the Caribbean Sea and Gulf of Mexico is studied using thirteen years of satellite altimetry data. In the Caribbean Sea, processes at several temporal scales are analyzed: the Caribbean eddies and meanders characteristics, the annual cycle and its variability through time, and the interannual variability, with a cycle of about 4 years affecting the SSH slope across the current and hence the ntensity of the Caribbean Current. Our analyses suggest that this cycle is related to changes in the wind intensity, wind curl and El Niño Southern Oscillation. In the Gulf of Mexico, the variability of the Loop Current is studied. We analyze the timing of anticyclonic eddy detachment from the Loop Current, the relation between the size of these eddies and the period between detachments, and the intrusion of the Loop Current into the Gulf of Mexico. A series of extreme Loop Current intrusions into the Gulf of Mexico, when the current is observed as far as 92°W, are described. The frequency of such events appears to have increased in recent years, with only one event happening from 1992 to 2002 (in 1993) versus three from 2002 to 2006. [less ▲]

Through analysis and an attempt to assess the system developed at the level of the Wallonia-Europe Academy in the context of Center for Higher Didactics (Centre de Didactique Supérieure : CDS), the purpose of this article is to reflect on the specificities and constraints of a training limited to teachers in charge of First Generation students, those specificities being especially constraining since the CDS training sessions take place in a larger context : the training of all the university teachers. The Liege experience enlightens some determinant factors : sensitizing first on the interest of such a training, centring the training on close coaching of students learning with a focus on their difficulties or deficiencies and with help given to teachers in resolving them, meeting the diversity of the situations lived by those teachers (notably in terms of students number and disciplines), taking into account their expectations in accordance with their profile, cleverly combining oral speeches, testimonies and debates, suggesting a diversity of concrete intervention trails… By the way, the joined organization of introduction sessions and close coaching seminars seems to be a relevant formula in order to meet such kind of objectives.

Time use surveys often are carried out to identify, classify and quantify social behaviour of people by focusing on the activities that people perform. Time use data, in the transportation field often referred to as activity-based data, can be used to study a variety of sociological, economic, and technological phenomena. Studying behaviour, social networks and transport patterns are a few of the topics that can be analysed based on these time use data. This first introductory paper discusses some emerging issues in the collection of travel-related data such as automatic spatial information recording using cell phones and GPS, and survey design experiences. On the one hand new technology offers the opportunity to record at a relative low cost a wide variety of the data, while on the other hand new problems occur. One of such problems for instance is the problems of ‘cold starts’ faced with GPS devices, clouding the first minutes of recording after each restart of the device after it was turned off completely. Notwithstanding, applications of new technologies offer the opportunity for performing detailed space-time analyses in different fields ranging from epidemiology to transportation science. Some of these applications are highlighted in this session. Next to the advantages and potential risks of new technologies, this introductory paper also discusses the combination of different modes to analyze space-time behaviour. In particular, this study investigates potential mixed mode design effects, observed in a large activity-based travel survey, using a PDA application on the one hand, and traditional paper and pencil diaries on the other hand. The mixed-mode effects are analysed using heteroscedastic linear regression models, taking into account not only mode-effects, but also potential fatigue-effects. The results show that in this mixed-mode survey no attrition effects are present, and that the survey mode (PDA versus paper and pencil) has no direct impact on the quantities investigated (number of out-of-home activities reported and number of trips).

Observations of Saturn's infrared aurorae have shown that in addition to the main auroral oval, which is believed to be associated with the solar wind, there are significant polar emissions. Ground-based infrared observations of Saturn have been able to show that there is a general level of raised emission across the entire polar region, in a similar way to that seen at Jupiter. However, with direct observations of the aurora made from orbit around Saturn by the Cassini-VIMS instrument, this aurora was shown to be more than a relative generalised brightening in the infrared. Instead, a unique auroral feature was observed to occur, appearing as a large region of bright polar emission, positioned poleward of 82 degrees latitude. This Bright Polar Aurora emission is significantly different from the recently observed subrotating Q-branch auroral emission seen in both the ultraviolet and infrared, as it is separated from the main auroral oval by a region of low emission. This effectively produces a cap of bright aurora inside the main auroral oval, surrounded by a dark ring that separates the two aurorae. Here, we take a more detailed look at this cap of emission and examine the way the auroral feature develops with time. Bright Polar Aurora emission has been observed in two separate VIMS images. A more detailed analysis of the polar emission shows that each of these images in fact differs in structure; the first has auroral emission across the whole polar cap >82 degrees, but within the second the emission is concentrated on the dusk side. While the dramatic in-filling of the polar cap is not seen within any UV observations, the Hubble Space Telescope has observed transitory duskward auroral features within the polar cap, in a similar location to the duskward feature seen in the infrared. Using ground-based infrared observations, which allow a Bright Polar Aurora event to be broken into shorter timescale steps, it is possible analyse the progression of the infrared auroral emission with time, connecting the morphology seen within the two VIMS images with those in the ultraviolet.

Background: Results of nonmyeloablative HCT in pts with HLA-mismatched donors have been disappointing due to high incidence of graft rejection and severe acute GVHD. Recent studies have suggested that infusion of mesenchymal stem cells (MSC) the day of HCT might promote engraftment and prevent acute GVHD after myeloablative allogeneic HCT. However, some studies suggested that MSC co-infusion might abrogate graft-versus-host alloreactivity and graft-versus-tumor effects. This prompted us to investigate whether MSC infusion a few hours before HCT could allow nonmyeloablative HCT from HLA-mismatched donors to be performed safely (i.e. with a 100-day incidence of nonrelapse mortality < 35%). Methods: 20 patients with hematological malignancies were given MSC (1-2 x 10E6 cells/kg) from third party donors a few hours before PBSC from HLA-mismatched unrelated donors, after conditioning with 2 Gy TBI and fl udarabine 90 mg/m. Postgrafting immunosuppression included tacrolimus (day -3 to +180; tapered by day +365) and mycophenolate mofetil (tid days 0 to +42). HLA-compatibility was assessed at the HLA-A, -B, -C, -DRBI and DQBI loci: 13 pairs were mismatched for at least one HLA class I antigen (including 4 pairs who were also mismatched for 1 HLA-class II antigens (n=3) or 1 HLA-class I allele (n=1)), 1 pair was mismatched for 2 HLA class II alleles, while 6 pairs were mismatched for a single HLA class I (n=3) or HLA class II (n=3) alleles. Results: Median follow-up for surviving patients was 288 (range, 76-571) days. One patient with secondary AML had primary graft rejection, while the remaining 19 patients had sustained engraftment. Median donor T-cell chimerism levels on days 28, 100, 180 and 365 after HCT were 90%, 98%, 96%, and 98%, respectively. Grade II, III and IV acute GVHD were seen in 5, 2 and 1 patients, respectively, while 7 experienced NIH moderate/severe chronic GVHD. Three of 7 patients with measurable disease at transplantation achieved complete remission on days 41, 104 and 353 after HCT. Two patients died of nonrelapse causes on days 74 and 114 after HCT, while 3 died of disease progression. Projected 1-yr overall and progressionfree survivals were 77% and 61%, respectively. Conclusions: HLA-mismatched nonmyeloablative HCT with MSC co-infusion appeared to be safe, with MSC co-infusion possibly mitigating graft-versus-host alloreactivity without abrogating graft-versus-tumor effects. Survival is encouraging. [less ▲]

Heaves is a common cause of recurrent airway obstruction (R.A.O) that occurs in mature horses stabled in a dusty environment. The long pentraxin PTX3 play an important role in the host defence and over-expression of PTX3 may contribute to airways injury. Therefore, we hypothesised that PTX3 may have relevance in the understanding of the pathogenesis of recurrent airway obstruction (R.A.O). In the present study, we first investigated the equine PTX3 (ePTX3) structure by cloning, sequencing and western-blotting. A 120pb deletion was found in the second exon of ePTX3 in comparison to human PTX3. Moreover, an alternative splicing occurs with complete deletion of the second exon, resulting in two forms of the protein, “spliced” (32 kD) and “full length” (42 kD). The pentraxin domain is very well conserved in the two forms with 94% of amino-acids conserved between equines and humans. These findings could have implications for the comprehension of the function of each domain of the protein. Then, we studied the effects of dust exposure and subsequent R.A.O crisis on ePTX3 expression in the broncho-alveolar lavage fluid (BALF) and the bronchial epithelial cells. PTX3 could be detected in BALF macrophages, neutrophils, eosinophils and bronchial epithelial cells. It was over-expressed in the BALF supernatant from RAO-affected horses in crisis. Dust exposure induced PTX3 in BALF macrophages either in healthy horses or in R.A.O-affected horses. Conversely, PTX3 was strongly over-expressed in the bronchial epithelial cells from R.A.O-affected horses in crisis. Considering epithelial cells as one of the major cell types in the airways, PTX3 produced at this level may play an important role in inflammatory process. Moreover, it suggests that dust-induced expression of PTX3 is differentially regulated in macrophages and bronchial-epithelial cells. A JNK-dependant, NFκB-independent regulatory pathway has been described in lung epithelial cells. A comparable mechanism could be involved in bronchial epithelial cells. If this is confirmed, PTX3 expression in respiratory epithelial cells could be therapeutically targeted. [less ▲]

Ce texte traite des politiques de lutte contre le travail des enfants au Burkina Faso dans une perspective historique, en cherchant à comprendre comment le travail des enfants a été construit comme « problème » dans les politiques publiques . Le but est d’explorer l’origine des politiques contemporaines de lutte contre le travail des enfants dans ce pays, en remontant aux politiques coloniales françaises en Haute-Volta, actuel Burkina Faso. Nous nous proposons de répondre à la question suivante : Face à l’émergence et au renforcement des politiques publiques de lutte contre le travail des enfants au Burkina Faso, assiste-t-on à un ratissage du modèle de l’enfant du lignage qui percevait l’enfant comme une « richesse » et une force de travail complémentaire? Ceci nous permettra d’analyser l’évolution et la portée de l’intervention des pouvoirs publics pour imposer une nouvelle vision de l’enfant (l’enfant de la Nation). Enfin, nous interrogerons la place réservée à l’ « enfant travailleur » dans ces politiques. [less ▲]

The aim of this experiment was to study the relation between the specific immune response and infection of slow-growing broiler chickens reared on straw litter contaminated by Campylobacter jejuni. The 11-weeks experiment was carried out in a 45 m2 broiler house with 500 chickens from 1 day of age, which had access to an open-air range. Litter contamination was performed before the setting up of the chicks by rearing campylobacter-positive cocks. These birds were also used to contaminate the open-air range during one week before the exit of the chickens, at 5 weeks of age. Blood samples were taken weekly on 20 chickens for anti-campylobacter IgG quantitative measurements on serum. Chickens were then euthanized and cecal contents and bile were collected for Campylobacter enumeration and anti-campylobacter IgA quantification, respectively. A high serum anti-campylobacter IgG titer of 110.13 was measured in one-day-old chicks. The IgG antibodies level significantly decreased to 5.60 at 28 days of age which coincided with the onset of Campylobacter infection in the flock. A significant reduction of the cecal colonization from 11 weeks of age was correlated with the increase in biliary IgA titers. These results suggest that the 2-3 week’s delay generally observed in poultry production before flock infection by Campylobacter may be, at least partly, explained by the protective effect of maternal antibodies. The increase of secretory immune response as bird age may help to limit Campylobacter population in the chicken gut. [less ▲]

Among natural factors driving the soil content in metallic trace elements (MTE), the geochemical background is often deemed as a sound base for the detection of contaminations. Numerous studies have shown the difficulties to take into account the multi-dimensionnality of the spatial variability of most soil properties. As far as a detailed soil map is available for Belgium, the relevance of its information was investigated at various spatial scales in the Walloon Region (Southern Belgium), from the plot to the entire region, to evaluate the feasibility of a multi-scale mapping of geochemical background. The soil properties of 410 plots from the regional forest soil monitoring and the relationships with informations related to the physical environment (lithology, soil types...) were investigated through multivariate statistical analysis. Some processes of integration of point measurements and qualitative information were also explored. At the regional scale, some long-range spatial structures could be identified. These result mainly from the geological structure of the Walloon region, where the lithological zonation is rather clearly marked. The soil map (texture and nature of stone charge) appears relevant at that scale too but does need a generalization process and fails however to differenciate the intra-type soil spatial variability.

The bonobo, Pan paniscus, an endemic primate of the DRC, forms with the chimpanzee, Pan troglodytes, the pair of species closest to humans. Classified as “Endangered” by the IUCN, it’s seriously threatened by the degradation of the forests. Only the creation of protected areas large enough and properly managed can improve its status but requires a good knowledge of the eco-ethology of the local populations. Our project will focus on studying a bonobo population recently discovered in the region of the Lake Tumba, in the west of the DRC. It is characterized by densities never encountered elsewhere, and a preliminary study has revealed significant differences in habitat and food resources in comparison to these of eastern populations. We will contribute to a recently established WWF conservation program by gathering eco-ethological data on bonobos, data that will allow identifying areas to protect, their boundaries and management measures to implement. To do this, we will study the diet of bonobos via direct and indirect observations of their behavior. We will also study the party size and its composition and identify underlying environmental factors. We will assess the bonobos’ home range size and pattern of displacement, which we will correlate with the abundance of food resources to determine whether there is a pattern of occupation of time and space specific to this population.

Crown rot disease of bananas is widespread in producing countries and is considered as the most important post-harvest disease of exported bananas. Variations of susceptibility to the disease have been noted between bananas but the origins still unknown. The biological responses of the fruit, including physiological change and disease susceptibility are controlled and regulated by gene expression. One way to understanding the reactions involved in variation of banana susceptibility to the disease in relation to their physiological state, is to study the expression of genes involved in these processes. To this purpose, crown sample previously inoculated with C. musae and showing 2 levels of susceptibility (very high and very low) were collected to be compared. Crown sample of each susceptibility level was collected at two different maturity stages: at harvest and 13 days after harvest (3 days after ripening). Collected crowns were immediately freeze-dried, an original method to conserve gene expression. cDNA-AFLP was applied on these 4 cell populations in order to highlight the differential transcription of genes whose function is "a priori" unknown. The cDNA-AFLP result was confirmed using quantitative real-time reverse transcription PCR. Various defence-related genes were identified and will be presented. [less ▲]

A top-down integration scheme for silicon vertical nanowire (NW) tunnel field-effect transistors (TFETs) with a 35nm nanowire dimension and using state-of-the-art metal gate and high-k gate dielectric is demonstrated. Using the short-gate concept [1], the ambipolar behavior of the TFET is successfully suppressed. The measured TFET performance is not yet beyond that of the MOSFET, most likely due to the use of silicon that has a large bandgap and the use of ion implantation for the formation of the tunnel junction which results in a low junction abruptness. To boost the device performance, a low thermal budget processing could be used on etched nanowires in a substrate with epitaxial grown junction, in order to increase the abruptness of the tunnel junction.
